Abstract

Weekly composite high-volume air and wet-only deposition samples were collected from April through September 1995 at paired urban and agricultural areas in Mississippi, Iowa, and Minnesota, and at a background site in Michigan?s Upper Peninsula. This report describes the methods used to collect, analyze, and quality assure the samples, and presents the results of all chemical analyses and quality control procedures. Each sample was analyzed for 49 compounds, including several pesticides not examined in previous atmospheric studies. Eighty-five percent of the herbicides, 70 percent of the insecticides, and 100 percent of the transformation products that were targeted for analysis were detected in one or more samples at each paired site.
